Mcu bsp engineer

Role purpose

Develop, configure, integrate, and debug MCU Board Support Package and AUTOSAR Classic basic software for automotive ECUs. The engineer will own OS, MCAL, power-management, Complex Device Driver (CDD), and I/O Hardware Abstraction (IoHwAb) activities from requirements analysis through target integration and validation.

Key responsibilities

• Develop and integrate MCU BSP software, startup code, linker configuration, memory mapping, interrupt handling, clock initialization, reset handling, and peripheral bring-up.
• Configure and integrate AUTOSAR OS, including tasks, events, alarms, counters, schedule tables, resources, ISR mapping, timing protection, and multicore considerations where applicable.
• Configure and validate MCAL modules such as Port, Dio, Adc, Pwm, Gpt, Icu, Spi, Can, Lin, Wdg, Mcu, Fls, Fee, and related interfaces based on ECU hardware design.
• Implement ECU power-management behavior using EcuM and BswM concepts, including ignition transitions, wake-up sources, sleep entry and exit, shutdown, reset, watchdog supervision, and low-power-state validation.
• Design and develop CDDs for hardware or functions not covered by standard AUTOSAR modules, with clean interfaces to RTE, BSW, and application software.
• Develop and configure IoHwAb components to abstract sensors, actuators, GPIO, PWM, ADC, pumps, valves, and other board-specific I/O from upper software layers.
• Perform board bring-up and hardware-software integration using schematics, datasheets, debugger traces, register inspection, oscilloscopes, logic analyzers, and bus analyzers.
• Analyze and resolve startup, timing, interrupt, memory, communication, power-state, watchdog, and peripheral-driver issues on the target ECU.
• Create and maintain software requirements, design descriptions, configuration specifications, interface documents, review records, and verification evidence.
• Collaborate with hardware, system, network, diagnostics, integration, application, safety, cybersecurity, and validation teams to close cross-domain issues.

• Hands-on AUTOSAR Classic configuration and integration experience, preferably on Infineon AURIX, NXP S32, Renesas RH850, ST, or an equivalent automotive MCU.
• Ability to read schematics and MCU datasheets and translate hardware design into software configuration and driver behavior.
• Strong target-debugging and root-cause-analysis skills, with disciplined use of logs, traces, measurements, and reproducible evidence.
• Ability to work independently across requirements, design, implementation, configuration, integration, review, and test activities.

Preferred qualifications
